The present invention"contemplates the l provision of a chamber,or/box`for comparatively heavy,r copyingcamer-as with p Whlch focusing'operations .may be readily icarried' out. Vj- To this fend; there is,provided a sitable number oybox-li'ke sections vwhichare'V-telescopically "associated--or;l -related,- v and means for;Supporting and.; adjusting the sections With respect toj-ifeaeh other,andy means for maintaining the proper alignment`of the*sectionsandforguiding and for causing the sections to move equally at each side oftheir major or longitudinal axes. In the. present instance three boX-like sections 10, 11 and 12 are provided to constitute a chamber or boxWith which Will be associated the object lens, shown at 13 carried bythe section 12, and a plate or film holder 14 associated With or carriedby the section 10. The section is of double Wall construction, therebeing a Wall 15 and a Wall 16 which are held in spaced relationship by aWall 17 attached to the Walls 15 and 16 by virtue of flanges 18 on theWalls 15 and 16 respectively. The Wall 17 is sub- 1926. serian No.109,128.l

In thisWay focusing operations are carried out; the section 11 moving'into thesection 10, Whereas the section 12 moves into the l sect-ion 11. Theflanges 24, 25, and 28 constitute a means for limiting the telescopicmovement oli' the several box-like sectlons.

In order to maintain the several sections in alignment, and for aidingin guiding the sections in their movements, and for causing thesect-ions to move equally at each side of their major or longitudinalaxes, there are provided pinions 38, carried respectively the sectionsand 12, and racks '39 car-'l by ried by the Walls and 21 respectively ofthe section 11. The pinions 38 are arranged in'pairs'ixed to an axle 40which is mounted in bearings 41. the racks 39 move either With respectAtothe pinions 3S. or are stationary While the pinions themselves rotate.y

It is to be noted that by making the Walls or plates 17, @Band end `Wall27 removable, it is possible to disassociate the severalboxlikesections. i In Fig. 3 there is shoivn a modiiication in which in lieu ofthe rectangular Walls or plates 17 and.

to the Walls with Which they are connected,

there is provided a Wall `which is ar r ranged at an angle so as todeflectany and are made of metal to give the desired strength andrigidity and to providel the proper degree of durability.

It is to be understood that the invention is not restricted to theprecise. arrangement of parts shownl and described, as details o'tconstruction may be modilied and rearranged Without departing' fromthe'spirit of the invention, the scope of which is limited only by theterms of the appended claims.
